Enabling a hidden engineering menu opens up access to deep operating system settings that are hidden by default from the average user. Many owners of Xiaomi, Redmi and POCO smartphones are wondering how to activate this functionality to speed up the interface or connect debugging.
The activation process is simple enough, but requires precise execution of the sequence of actions in the settings menu. Misconception of settings in this section can lead to unstable operation of the device, so it is important to understand what each option is responsible for.
In this article, we will take a detailed look at all the activation steps, review the purpose of key features, and give answers to frequently asked questions so that you can safely use the full potential of your gadget.
Why you need a developer mode on MIUI and HyperOS
The main purpose of this section is to provide tools for testing applications and debugging code by programmers, but advanced users use these capabilities to fine-tune system performance and manage power consumption.
One of the most popular features is to change the animation speed, which allows you to visually speed up the response of the interface, and there is also the option of debugging over USB, necessary for data transfer, installing applications from a computer or using specialized software like Mi Unlock.
In addition, in this section, you can forcefully change the refresh rate of the screen, activate the display of touches to create screencasts or limit the background operation of processes to save battery power.
⚠️ Warning: Changing the values in the For Developers section can lead to system instability or loss of data, so do not change the settings, the purpose of which you do not know.
Step-by-step instructions for activating the hidden menu
To access the advanced settings, you need to click a certain sequence in the About Phone menu, a standard security measure implemented by Android developers and adapted into the MIUI shell.
First, open the Settings app and go to the topmost section of About Phone. Find the line MIUI Version (or OS Version in newer versions of HyperOS) and quickly tap it 7-10 times in a row.
After a few clicks, a pop-up notification with a countdown will appear, followed by the message “You became a developer!”. Now a new item “For developers” will appear in the “Advanced Settings” menu.
☑️ Verification of activation
If the notification doesn't appear, make sure you click fast enough and hit the right area of the screen with your finger, with some models requiring up to 10 clicks.
Configuring debugging over USB and security
USB debugging is critical for deep-level smartphone-computer interaction, allowing you to send ADB commands, install applications directly from the IDE, or restore the device in the event of software failures.
To activate, look for the USB Debugging Switch in the developer menu and activate it. The system will give you a risk warning to accept, and the first time you connect to a new computer, you will see a request for RSA key confirmation on your phone screen.
It is important to always check which device you are giving access to, and confirming an unknown computer can give an attacker full control over your data if the device falls into the wrong hands.
⚠️ Warning: Never leave debugging mode on permanently unless you’re using it right now, as this creates a potential vulnerability when connecting to public charging stations.
You can also set up Wi-Fi Debugging in this section, which allows you to connect to your device wirelessly from the same network, which is convenient for wirelessly transferring large amounts of data or screencasting.
Optimization of the interface and animation
One of the most notable improvements available after enabling developer mode is the ability to speed up the interface. Android animations are 200-300ms long by default, which creates smoothness but can be perceived as a delay.
Find the section "Drawing" and the parameters "Scale of window animation", "Scale of transition animations" and "Duration of animations." Change the value from the standard 1x to 0.5x or even 0x for instant response.
💡
Setting a value of 0.5x instead of 0x keeps the transitions visually smooth, but makes them twice as fast, which looks more natural to the eye.
Here you can also turn on the option “Download fonts” if you use custom themes, or activate “hardware acceleration” for rendering if there are failures in the graphics.
Do not set minimum values on older models of smartphones, as this can lead to skipping frames and a twitchy image when scrolling.
Process and memory management
The Apps section of the developer menu allows you to control the behavior of running programs. The Inactive Applications feature allows you to limit the background activity of rarely used programs to save resources.
The Background Process Limit option allows you to rigidly specify the number of applications that can stay in memory. This can be useful on devices with low RAM, but on modern flagships it is better to leave the value of Standard.
Also available is the "Remember Apps" feature, which compulsorily keeps selected programs in memory, preventing the system from unloading them, which is relevant for navigators or messengers that need to work constantly.
Using the “Forced Activity in the Background” feature can significantly increase battery consumption, so use it only for necessary services.
Network settings and location
The Network section hides tools for testing connections, where you can force the type of network to switch, for example, to make the phone only work in LTE or 5G mode, ignoring older standards.
The option of Always Turn on Wi-Fi Scanning and Always Turn on Bluetooth Scanning allows applications and services to search for devices even when the communication modules are off.
Location emulation tools are also useful for application developers, and you can set up bogus GPS coordinates to test whether geo-dependent services or games are working.
| Parameter | Description of function | Impact on the system |
|---|---|---|
| Window animation | Application Opening Speed | Visual acceleration |
| Background processes | Application limit in memory | Saving RAM |
| USB debugging | Access to ADB and files | High security risk |
| Show touch | Visualization of pressing | Convenience for screencasts |
Using these settings requires understanding exactly how your smartphone interacts with the network so as not to disrupt the stability of the connection.
Possible problems and solutions
Sometimes, after enabling the developer mode, users are faced with unexpected system behavior, for example, constant notifications about connecting debugging or resetting network settings.
If you notice that the phone is running out quickly, check if you have activated the Always Scan feature or set a too tight limit on background processes, forcing the system to constantly restart applications.
How to reset all the developer settings?
In case of problems with connecting to your computer, try to disable and re-enable debugging over USB, as well as check the integrity of the cable.
⚠️ Attention: Factory Unlocking Function» (OEM unlocking) is only necessary to unlock the bootloader; enabling it unnecessarily can reduce device security.
Remember that resetting the developer settings does not delete your photos or contacts, but returns all engineering settings to the original state.
